Abstract

The invention relates to the field of lighting engineering, namely to the design of a flashlight, and prevents the spontaneous closing of the power supply circuit of the light source. The flashlight includes a housing 1 with a power supply element 2 installed therein, one pole of which is connected to the spring housing 3, and the other pole with a central outlet 4, a socket of the glow lamp 5. The thread portion of the socket of the glow lamp is fixed in the cartridge 6, having 8 bends, fixed in an optical assembly 9 with a lens 10. A contact plate 11 is fixed to the housing 1 with a push button 12 and an electrically conductive pin 13 having a dielectric tip 14 at the end, designed to interact with longitudinal slots 7 made in throne 6. An optical unit 9 is connected pivotally to the housing 1 rotatably lengthwise axis of the lantern. 2 Il. (L S yu SP

Description

one

Ichobochig- refers to lighting, and in particular to the design of pocket lamps.

The aim of the invention is to prevent the inadvertent closure of the power supply circuit of the light sources.

FIG. 1 shows the design of a pocket lamp, a common VKT; on fng. 2 - elements of the power circuit of the incandescent lamp.

The flashlight contains a metal case 1 with a power supply element 2 2 installed in it, an electric power supply element 2, a sub spring, a body with a conical spring 3 that connects one pole of the electrochemical cell with the body, the other body of the electrochemical cell is connected to the central 1 and c) D) lamp base 5 incandescent. The thread part of the incandescent lamp base is fixed in the socket 6, made in the form of a metal cup, installed coaxially to the body 1A of the incandescent lamp 5. In Paton 6, there are longitudinal slits 7, and the edges have 8 bends fixed in the optical unit 9, facing the focus lens 10 in the front part. The optical unit 9 is connected to the body 1 pivotally with the possibility of rotation along the axis of the lamp.

On the housing 1, a metal face contact plate 1 1 is fixed with a push button 12. At the end of the contact plate there is an electrically conductive plug 13, at the end of which a dielectric tip 14 is made, for example polyamide. The diameter of the dielectric tip 14 is larger than the diameter of the electrically conductive pin 13 and smaller than the pitrina of the slots 7.

Lantern works as follows

When the lamp is activated, it is necessary to hit the button 12 and simultaneously rotate the optical assembly 9. When the contact plate 11 is deformed, the pin 13 sinks and begins to interact from the side 68

By the surfaces of the longitudinal slots 7 of the cartridge 6, turned together with the optical assembly 9. The power supply circuit of the incandescent lamp 5 is closed.

When the force is removed from button 12, dielectric tip 14 holds contact plate 11 in the locked position and the power supply circuit of the incandescent lamp remains closed.

To turn off the lamp, it is necessary to turn about (.) The yuma 9 together with the cartridge 6 in the opposite direction until the dielectric tip exit 14

from the slots 7. The contact plate 11 is returned to its original position by the action of elastic forces. At the same time, the power supply circuit of the incandescent lamp 5 is opened.

The proposed design of the flashlight ensures its reliable operation by eliminating the possibility of inadvertently closing the power supply circuit of the incandescent lamp and

the subsequent non-contact bit gal1) Vanical element.
